Problems solved by technology

[0006] The amount of reagent disclosed in the above-mentioned documents is relatively high, which will lead to the problem of increased production cost
This situation is mainly due to the failure of the existing organic vanadium removal reagents to generate fine carbon particles quickly, so it is necessary to increase the amount of organic vanadium removal reagents to achieve the carbon content required for the vanadium removal reaction

Embodiment 1

[0043] In Example 1, Example 2 and Example 3, except that there are multiple choices of raw materials and their contents, other reaction conditions and parameters are completely consistent.

[0044] Table 3 shows the composition, physical properties and effect evaluation of compounded organic matter. The evaluation methods in Table 3 are as follows:

[0045] Measure 200ml of crude carbon tetrachloride, add 1ml of the compound oil of the example, and stir in cold state for 90-120min, then distill at 130-140°C, collect refined titanium samples, and carry out vanadium content and chromaticity detection. The vanadium content in the test result is less than 1ppm, and the chromaticity is less than 5mgK 2 Cr 2 o 7 / L -1 time is qualified.

[0046] According to the result of evaluating the effect, it can be seen that the addition amount of copper-loaded graphene oxide has a significant influence on the vanadium removal effect. When the addition amount of copper-loaded graphene ox...

Abstract

The invention belongs to the field of purifying titanium tetrachloride with organic substances, and particularly relates to a compound organic substance for efficiently removing vanadium from crude titanium tetrachloride. The organic substance comprises: organic base oil, aromatic hydrocarbon oil, silicone oil, graphene and metal chloride, wherein the mass ratio of the components is (40-70):(2-10):(10-30):(5-10):(2-10), successively. The organic base oil is mixed white oil; the aromatic hydrocarbon oil is dimethylaniline; the silicone oil is dimethyl silicone oil; the graphene is copper-loadedgraphene oxide; the metal chloride is zinc chloride. The organic substance is easy to catalyze and crack, the vanadium removal efficiency is high, and the vanadium removal dosage is low.

Description

technical field [0001] The invention belongs to the field of refining titanium tetrachloride from organic matter, and in particular relates to a composite organic matter for efficient removal of vanadium from crude titanium tetrachloride and a preparation method thereof. Background technique [0002] High-purity titanium is widely used in the aerospace field. The purity of titanium tetrachloride can directly affect the quality of titanium products for aviation. It is required that the content of pure titanium tetrachloride should reach 99.95%. In the process of refining titanium tetrachloride with organic matter, there is a problem of high addition of vanadium-removing reagents. The reason for this problem is mainly due to the slow cracking of organic matter, resulting in low carbon content involved in the reaction of vanadium removal, which affects the crude titanium refining process. removal efficiency. Therefore, in the process of refining titanium tetrachloride, it is n...
